Application filed September 25, 1906. Serial No. 336,202.

To all whom it may concern:

Be it known that I, PAUL FONTAINE, a citizen of the Republic of France, residing at Troyes, Aube, France, have invented new and useful Improvements in Dyeing Apparatus, of which the following is a specification.

The present invention has for its object an apparatus for dyeing threads on bobbins.

The invention facilitates the formation of a completely-closed liquid circuit in which bobbins are mounted above the orifices of a perforated partition of a vat which on both sides of the partition communicates, respectively, with the suction and delivery of an exhaustion and feeding pump, the closing of the circuit being effected after the complete exulsi'on of the air by the liquid dye. The iquid dye, which is thus provided in constant quantity v ery exactly determined, is adapted to be forced through the bobbins alternatively from without to within and from within to without and always' produce a correspondingly-defined tint. It will be certain with a bath of determined composition to reproduce at each operation the same tint if` the apparatus is made to work during the same time at the same temperature and with the same alternation.

The annexed drawings represent, as aV representative example, a practical form of construction of the apparatus embodyingthis invention. j

Figure 1a is a sectional elevation of onehalf of the apparatus. Fig. 1b is a similar view of the other half of the apparatus. Fig. 2a is a plan view of one half of the apparatus. Fig. 2b is a similar view of the other half of the apparatus. Fig. 3 is a side elevation of a part, Fig. 4 is a sectional elevation showing a'contrivance for removingthe perforated partition. Fig.'5a is a sectional elevation of assembled means for fixing the bobbin-carrying spindles on the perforated partition. Fig. 5b is a vertical sectional view of a perforated spindle upon which the bobbin may be mounted. Figs. 6 to 11 are elevations and plans in detail of the parts of this contrivance.

The apparatus comprises a vat, preferably made in three parts a b c. The upper part et consists of a ring of inverted-U section, from the exterior wall of which emerges at f one of the passages d of the pump e, adapted to operate with the same volume of delivery in ternally with a stop-cock m, serves for the escape of air or eventually some of the liquid dye itself on its introduction. The intermediate ring b is joined to the upper and lower portions a, and c. It carries on its upper edge a flange n. Between the interior edge of this flange and the edge of the interior wall of the ring a is provided an annularslit o for the escape of the liquid. A serpentine coil p, whose inlet and outlet are situated outside the vat and commanded by valves, is disposed against the interior Wall of the ring b. It receives live steam for heating purposes.

The lower element c of the vat is formed as a truncated cone, the small end of which, situated below, is joined to a tubular branch q, by which it is connected to a pipe r, formingone of the passages of the pump e, (suction or delivery, according to the direction of flow.) To the pipe 1" is branched an evacuation-pipe s, provided with a turn-cock t, and on a lateral branch 13 is joined an inlet-pipe provided with a turn-cock. (Not shown.)

In a groove u, rormed around the edge of the upward-situated base of the truncated cone c, rests a metallic j oint-ring c, on which is close pressed the downward-bent edge of a perforated diaphragm w of the form of a spherical cap. In the orifices of this diaphragm are mounted the perforated spindles on which are carried the bobbins y, vs ith or without a central core of perforated cardy board. An `axial rod .e passes through the cover y', the diaphragm w, and the bottom tubular branch q through a projection Z, It is screw-threaded at its two extremities 1 2 and carries at an appropriate level a collar 8a. On the threads 1 and 2 are screwed, respectively, the securingnuts 3 and 4. These nuts are shown as made in two parts connected by pins, the core, being of the harder metal, adapted to be easily replaced when it is worn by use. The nuts 3 and 4 apply pressure, respectively, on the projection Z and on the cover j, and the collar 3 presses itself on the diaphragm w.

The apparatus is furnished with a thermometer 5, a safety-valve 6, and a manometer 7, mounted on the passage d.

The vat is represented as supported on a base 8, the construction of which can be varied as required.

The working of the apparatus is as'follows: Suppose the vat empty and the lower nut 3 suspended to the vat, for example, between the branches 9 of a loop carried by the tubular projection Z. The cover having been lifted by its jointed handle 10 and the rod e withdrawn, the diaphragm w is removed by means of a screw-threaded rod, such as l1, Fig. 4, screwed into the aperture provided for the passage of the rod e. In order to proceed with the assemblingk of the apparatus, the diaphragm charged with bobbins to be dyed is inserted in place, the axial rod is then passed through the central orifice of the diaphragm and the tubular projection Z and secured by screwing on the thread 1 the lower nut 3, which remained suspended from the vat, the collar 3 being thereby close pressed onto the diaphragm. The cover is then replaced, the handle turned downward, and the'nut 4 is screwed on the'thread 2. The exit turnecocks t and 12 are then closed, and the turn-cock of the passage from the liquiddye receptacle which is connected with the inlet branch 13 is opened and also the stopcock m for the escape of air. Finally the pump e is put in action, drawing the liquid by the passage r and delivering it by the passage d, care being takenl to place the bottom ofthe dye-container above the level of the diaphragm w. The apparatus being full of liquid, which will become evident as soon as it appears at m, this latter as well as the admission turn-cock are closed, and the pump is continued working in the initial direction during the half of the time fixed for the operation of dyeing. As the apparatus is perfectly closed the body of the bobbins will be.

traversed from top to bottom by a determined quantity of liquid in a unit of time. The direction of the Working. of the pumpis then changed and the liquid forced in a reversed direction from the bottom to the top. V'hen the time assigned for the dyeing has passed, the pump e is stopped, and the stopcock m and draw-olf turn-cocks 12 and t are` opened. The vat being emptied, the nut 4,l

the cover and the diaphragm are removed. rThere remains nothing more to do than to withdraw the bobbins and hang them in the air in order to dry.

Figs. 5 to 11 show a practical form of construction of a device for fixing on the diaphragm w the perforated spindles on which are carried the bobbins y. In each of the conical orifices of the diaphragm w is inserted aI sleeve 14. (Shown in section in Fig. 5 and in elevation, plan, and inverted plan in Figs. 9, 10, and 1l, respectively.) This sleeve, in

the interior of which there is a longitudinal groove 15, is formed at the bottom end with a helicoidal surface 16. With the sleeve 14 15 16 engages a second sleeve of two external diameters 17 18, formed at its lower extremity, with a bent spur 19. This second sleeve is shownrseparately in elevation, plan view, and inverted plan in Figs. 6, 7, and 8, respectively. The perforated spindle is mounted in the upper part 17 of the sleeve 17 18. The spur 19 is passedl through the groove 15 of the sleeve 14 l15 16, and then by a rotation of this spur when it protrudes through the groove it is pressed on the helicoidal surface 16, The element 14 l5 16 of this bayonet-joint can of course, instead of being independent of the diaphragm-platew` be cast with this latter. Two indentations 20, made in the sleeve 17, facilitate the fixation by means ofva wrench.
